Cheap Birthday Party Locations for Adults

I need to throw a cheap 40th Birthday party for Sister-in-Law! We would love to do a party at a club or bar but we all know how expensive that can be! We all like to drink and enjoy music. My home is too small to house all the people we need to accommodate. Please assist with ideas, I want to make this day special.Thanks so much!

Rent an Elk's Club or American Legion meeting hall. Have a karaoke machine and DJ.

For his mother's 40th BD, my stepson appeared out of a cake as a Chippendale-type guy in thong and bow tie! She didn't know he would be there, and was totally rocked out by it once she recognized him!.

Or have a party in a food serving place that's usually closed then, like in a bakery. Or in a recreation hall for a living complex, or a senior center building.
